<p>PURPOSE:To downsize, to reduce the number of assembly processes and cost, to prevent occurrence of noise and to improve reliability. CONSTITUTION:An area A where a coil parts M is configured is assured an a portion of multilayer substrate 2, and multiple unit substrates 2a,..., corresponding to the area A are provided with coil patterns 3a, 3b, 3c,..., and the coil patterns 3a,..., of the laminated unit substrates 2a,... are connected through a through hole T,..., so that a coil parts M is constituted. Then, the printed substrate 1 is attracted to another printed substrate for configuration.</p> |
